      Joint Real-Time Scheduling Methods for Deterministic Industrial
                          Field/Backhaul Networks

Abstract

   In industrial field/backhaul networks, joint real-time scheduling
   method is important to make end-to-end flows meet their deadline.
   This document proposes four joint scheduling methods, and they
   involve four scenarios: time-slotted industrial backhaul network,
   regarding industrial backhaul network as a black box system,
   ignoring delay of industrial backhaul and establishing latency model
   of industrial backhaul network.

1. Introduction

   Industrial field networks are often deployed to process control
   industry to monitor industrial field equipment. Industrial field
   network can improve production efficiency, reduce human intervention
   and decrease cost, which are significant for industrial
   modernization.

   Industrial field bus and industrial Ethernet are two kinds of common
   networks deployed in industrial automation, while they are wired
   networks. With the development of industrial wireless technology,
   Wireless Sensor Networks (WSN), a typical industrial wireless
   network, has been applied to industrial network. WSN can free
   traditional field devices from the limits of abundant cables, and it
